The reason that water soluble molecules cannot enter certain regions of the plasma membrane is due to the presence of?
gated channels which close when ions are present
The hydrophilic regions of a membrane protein are most likely to be found?
The hydrophilic regions of a transmembrane protein are likely to be found on the exterior of the membrane. The transmembrane protein may have three parts: a hydrophilic segment, a hydrophobic segment, and another hydrophilic segment. The hydrophobic region would be in between the hydrophilic regions. The hydrophobic region will be embedded in the membrane and the hydrophilic regions will be on the inside and outside of the membrane.
What is the function of the peripheral protein?
Peripheral membrane proteins are proteins that adhere only temporarily to the biological membrane with which they are associated. These molecules attach to integral membrane proteins, or penetrate the peripheral regions of the lipid bilayer. The regulatory protein subunits of many ion channels and transmembrane receptors, for example, may be defined as peripheral membrane proteins. In contrast to integral membrane proteins, peripheral membrane proteins tend to collect in the water-soluble component, or fraction, of all the proteins extracted during a protein purification procedure. Proteins with GPI anchors are an exception to this rule and can have purification properties similar to those of integral membrane proteins.
How do cells use the process of osmosis and diffusion to take in nutrients and to get rid of wastes?
== == Diffusion is: the movement of particles from regions of higher concentration to regions of lower concentration. Osmosis is: the diffusion of water through a semipermeable membrane.
What process occurs as water moves from regions of higher water concentration to regions of lower water concentrtion across a selectively permeable membrane?
Osmosis

How do nonpolar regions of a membrane proteins cause proteins to be held in the membrane?
IB sucks

What are the three main regions of the cell from the outside in?
Cellular membrane, cytoplasm, nucleus.

Why can TV channels of lower numbers give better pictures in regions of poor TV reception?
Diffraction around buildings is easier for TV signal in lower numbered channels.
What process occurs as water moves from regions of higher water concentration to regions of lower water concentrtion across a selectively permeable membrane?
Osmosis
The process of “diffusion” through a membrane may be described by which of the following ?
: the movement of ions and molecules away from regions where they are in high concentration towards regions where they are in lower concentration.
What channel is Root TV on Direct?
Root Sports on DirectTV is located on a few different channels. The channels are 687 and 688. Root Sports may only be available in certain regions of the United States.

Describe how dissolved particles move across a plasma membrane form regions of lower to higher concentrations?
Things move across the membrane from lower to higher concentrations by active transport.
